Over the years, I've experimented with dozens of plastic trailers for the specific use of spoon tipping......I have pictured below, 5 of the most productive plastics I've encountered.
Pictured left to right, Southern Pro's 1" Lil' hustler.....Berkleys' 1" Power tube....Bass Pro's 1 1/2" Squirmin' squirt.....Venom lures 1 3/4" solid bodied tube....Herb Reeds 2 1/2" Fin-S minnow (trimmed).
These plastics are ideal for spoon tipping and should be glued onto the hook with Berkleys' anglers glue....The lower pic is of a fully rigged 1/12 oz Kastmaster, with a Venom 1 3/4" solid bodied tube bait trimmed back 5/16 of an inch....these solid bodied tubes sit on the top of my list due to the durability of the plastic, and the ability to get good glue adhesion. This total package measures 2 3/4", and has been known to be attacked by gills up to 10" and as small as 4".
